Effects of different extracts of the mushroom Agaricus blazei Murill on the hematologic profile of mice with Ehrlich tumor

The aim of this study was to investigate the effect of the mushroom Agaricus blazeii Murril (ABM) extracts on the hematological profile of Swiss mice bearing an Ehrlich solid tumor. Three fractions (total extract, polysaccharides, and supernatant) of ABM extracts obtained by four methods (ultrasonic or water bath, at pH 4 or pH 7) were administered to mice over 21 days. Polysaccharide solutions were analyzed by gas and liquid chromatography that showed both mannose and glucose concentrations. The method of extraction influenced the degree of glucose polymerization and the mannose/glucose relationship. The treatment with ABM supernatant at pH 7 and water bath was associated with reduced concentrations of leukocytes and lymphocytes and altered the percentage of CD4+ and CD8+ lymphocytes in Ehrlich tumor-bearing mice. The treatment with the ABM extract in water bath and ultrasound at pH 4 resulted in lower lymphocyte counts, regardless of tumor presence, and greater granulocyte values in mice with Ehrlich tumor than in controls. We concluded that different fractions and methods of extraction of A. blazei produced differing blood profiles in mice inoculated with the Ehrlich tumor.
